The "standard" way to do this is to use the keyboard-translate-table.
This is an array of characters that emacs uses to translate the
characters it receives into other character before it interprets them.
This is what I have in my .emacs file:

    (progn
      (setq keyboard-translate-table (make-string 128 0))
      (let ((i 0))
	(while (< i 128)
	  (aset keyboard-translate-table i i)
	  (setq i (1+ i))))
      (aset keyboard-translate-table ?\^^ ?\^q)
      (aset keyboard-translate-table ?\^\\ ?\^s)
      (aset keyboard-translate-table ?\^? ?\^h)
      (aset keyboard-translate-table ?\^h ?\^?)))

This maps C-\ to C-s, and C-^ to C-q.  So, whenever you want to type
C-s, you use C-\ instead.  It also switches C-h and DEL, which is useful
if you are using a terminal that uses C-h for backspace instead of DEL.
If you have problems with your terminal sending C-s and C-q for flow
control, and emacs interpreting these as isearch-forward and
quoted-insert, use the command (set-input-mode nil t) in your .emacs
file.  This will tell emacs to use CBREAK mode, and use C-s/C-q for flow
control.
